To all 'whom it mag] concem: l

Be it known that we, BENGT M. W. HAN- soN and FREDERICK C. ALLEN,citizens of the United States, residing at Hartford, in the county ofHartford and State of Connecticut, have invented certain new and uselfulImprovements in Shapers, of which the following is a specification.

This Iinvention relates to Shapers.

Our improvements can-,be incorporated with utility in various styles ofmachines of the character mentioned.

In the drawings accompanying and forming part of the presentspecification, we have illustrated in detail one convenient form'ofembodiment ofthe invention which will be set forth fully in thefollowing descri tion, this disclosure being primarily provi ed toenable lthose skilled in the metal-working art to practice theinvention. We may depart .from such disclosure, however, in severalrespects within the scope of the claims, without departing from thespirit of the invention. i

In the organization illustrated the l machine is a vertical shaper,although this is not essential, it being immaterial in what directionthe tool travels. A n

A machine involving our invention comprises several features ofadvantage, one being the effective means whereby the range of movementof the tool can be. adjusted without'afecting the proper feeding of theworkcarrying means. Anotherpoint resides in means for feeding the toolwith a minimum expenditure of ower. Another point is the swiveling of te tool-supporting head so that when the tool has cut upon one face ofwork, said head may be turned to cause the tool to operate upon anotherface of work, by reason of which no adjustment need be touched unless ofcourse we, except the adjustment of the head. Another point is thesubstantialV mounting and bracing of a swinging member of thetool-supporting head so that chattering or shake is reduced to the leastpossible extent. The machine involves other features of novelty andadvantage which with the foregoing will be set forth fully in saiddescription. IVe might remark that it is notl necessary that all ofthese features be employed in one machine.

'is a sectional detail of a portion of slideadjusting mechanismhereinafter described.

Fig. 4 is a detail view in elevation, of part of the gearing foroscillating the tool-carrier. Fig. 5 is a similar view of a camconstituting part of the slide-feeding mechanism.

The views are on different scales, and throughout the same likecharacters refer to like parts. y

The different` parts of the machine may be supported upon any suitableframework; that shown comprises a hed 10 and a column 11 risingfrom andsuitably fastened to said bed as by bolts, as is usual in metal workingmachines of various kinds. Upon the bed 10 is the main slide 12 whichhas a has preferably imparted thereto after the4 usua fashion, a rockingor oscillatory movement. That is to say it is common in this artto'operate by power during one period of action one of the two slidesand to operate at a diderent time the other of the two' slides also bypower.` For example when the slide 12 is being operated by the power ofthe shaft 16 the slide 13 will, if necessary, be adjusted by hand,whereas when the slide 13 is being operated through the agency of saidshaft 16 the slide 12 iffnecessary, is operated by hand. The main slide12 may be operated by the hand-wheel 17 and its usual adjuncts, whilethe hand wheel 18 and its appurtenances may be employed for operatingthe cross slide 13, the hand wheel 19 and devices connected therewithbeing provided to rotate the turntable 14. The feed screws 2O for theslides 12 and 13 may be provided with ratchet wheels 21 engageablepreferably by pawls 22 which in turn are actuated by the shaft 16 all ascommon in shapers of various types.

action, so that said pawl can, through the in termediate parts operatestep by step itsiappropriate slide, this action occurring after i a cuthas been made by the tool.

Thehead or overhanging portion of the column 11 is provided with asuitable slide- .just described permits carrier and to the slide thereonas will hereinafter appear, is connected the shaping tool. Aslide-carrier such as answers our purpose, is that denoted in a generalway by 25 and which may as shown, be pivotally supported as at.2G at itsupper end, to the top of the column 11. Owing to the pivotal mounting ofthis carrier it is adapted for angular adjustment, and it may bemaintained in its `adjusted position by bolts as 27 extending througharcuate slots 28-near the lower part of said carrier, said bolts `beingprovided with nuts on the outer sides of the column. By loosening thenuts the carrier 25 can be swung either forward or backward to adjustthe tool connected therewith and when the adjustment is obtained thenuts will be set up, to clamp the carrier substantially in place. Itwillbe seen that the organization this carrier to be swung-about ahorizontal axis which provides for one adjustment of the tool, a secondadjustment of said tool being secured by means hereinafter described.The carrier 25 supports a tool-slide as 30 which is reciprocated bypower as will hereinafter appear, and the mechanism for operating saidslide is such that the stroke of said slide and therefore of the toolcan be varied. Means are also provided foradjusting said tool slide 30lto govern the position of cut all as will hereinafter appear.

A tool such 4as meets our requirements is that denoted by '31 and it issustained by a head such as that denoted in a general way by 32, saidhead being 'swiveled to the slide 30 for movement about 'a verticalaxis, for instance by having the body or main portion 33 of the saidtool-carrying head 32 connected by a bolt or stud '34 with said slide30, the head of said bolt or stud being located in a chamber 35 in saidbody 33 and the shank thereof fitting a hole in the web 3G of said slide30. The shank of the stud or -bolt is perforated to receive theclamping` member 37 which is made in the form of a stud shaft having acam portion 38 situated in the hole or perforation of said shank, saidlocking or clampingmember 37 boing equipped with a handle or lever 39.The cam portion 38 on the manipulation of the handle, 39, is adapted toforce the tool carrying head 32 upwardly into solid engagement with theslide 30 as shown in Fig. 3, thc head of the pivot pin or bolt 34 atthis time engagingthe top or roof of the chamber 35. To adjust the head32 the cam shaft 37 will be turned so as to cause the `cam 3S to freethe pin or stud 34 at which time said head 32 can be turned toaccomplish the desired object at which point the cam shaft 37 will beoperated so as to eect the clamping of the head 32 against the slide 30as already described. In addition to the body 33 the tool-head 32 has aswinging member pivoted to said body at 41, and this swinging bod'ydirectly carries the tool, said swinging member 40 being furnished witha tool post 42 the stemv of which is providedwith a-nut 43 adapted toengage against the outer surface of the swinging -member 40. The head ofthe tool post 42 has a-perforation to receive the tool 31 and the toolis adapted to bc drawn against the hard metal facings 44 by the actionof the nut 43,'

said facings being pinned or otherwise secured to the front face of theswinging member 40. It will be observed that the outer surface of thetool post42 or its equivalent is back of thecutting edge or point of thetool 31 and therefore back of the cutting plane by reason of which thetool can 'ont entirely through work, no matter what its depth orthickness, without interference.

In a shaper the cut usually takes place on the advance of thetool-carrying slide, and during the cutting operation by the tool 31 thethrust against theA tool is in the opposite direction, and this effectis transferred to the swinging member 40 which has a flat surface 45adapted to bear against a similar flat surface 46 on the body member 33so' that during the cutting operation the effect is as vthough'the-swinging member 40 were -rigid or integral with the body member 33.

During the retractive stroke of the parts the' swinging 'member 4()lpermits the cutting portion of the tool 31 to lightly travel against thework without cutting and if any obstruction iscncounteredtduring thebackward modiemert the swinging member can, of course, give, and in thisway the work will not be marred. As a matter of vfact in the presentcase we provide means for yieldingly receiving thethr'usts of theswinging lmember on backward movements thereof,

and for thispurpose thel spring 47 may bc provided, said spring beingcoiled about a pill 48 disposed in tht chamber and rigidly connectedwith the body 33, one end of the spring bearing against said body 33 andthe other end bearing against the Alug or ear 49 rising from saidswinging member 40 so adsense that when the tool 31 strikes any'obstruction or protuberance on the-backward movement thereof, the shockis buded or taken up' by said spring. There may becases where it isdesirable toprevent movement of the swinging member i0 on the retractivemotion of a shaping tool such for example as where a very long tool isbeing used, and to secure this result the screw 56 for' example may beutilized. rlhis screw is tapped through the 1u or ear 9 on the swingingmember 40 and normally its tip oninner end is free of the pin 48. If thescrew 50 is operated so as to cause it to engage the pin 48 the swingingmember 40 will be eectu- .allylocked against all movement relatively tothe body 33.- We also call attention to the fact thatthe tool ost 42 issituated between the axis of oscil ation of the swinging member 40 andthe abutment surface 46 so that thereby we get maximum holdingeiliciency-of said swinging member 40 by the body member 33 duringcutting. |lfhe best effects are secured when the axis of oscillation ofthe swinging member 40 is diagonally opposite the abutment surface d6 asshown.

As a means for reciprocating the slide 30 the lcver l55 may be provided,and although the effect of said lever may be transferred to said slidein any desirable manner, we prefer block 56 to which said slide isconnected for' that \it be applied to a. member such as the adjustmentfor a reason that will hereinafter appear. The slide 30 is provided witha screw 'shaft 57 which is longitudinallyimmovable iii the slide and thethreaded portion ofl which is tapped into the block 56. It will,therefore, he clear that by rotating the shaft-*57, the slide 30 may befed up and down. Any suitable Ameans may be provided for rot-ating' theshaft 57. It is shown provided with a spurgear-58 in mesh with thespur-gear 59 rigid with the shaft 60 also carried by the slide '30 andat the upper end thereof, said stub shaft 60 being provided with a handwheel 6l.. Therefore by'turning the hand wheel 61 the slide 30 throughthe intermediate parts may be adjusted vertically on the carrier 25 andwith respect to the block 56, whereby the point at which vthe cui; is tobe made can be regulated. The

sustained by bearings carried by the sides of the column 11 in whichcolumn said shaft 55 is located, the column having a slot 64 at its rearto permit free swinging movement of said lever 55. The rear branch ofthe lever has a longitudinal slot 65 in which the block or shoe 66 issituatedl/ said block or shoe being of rectangular construction .andfreely fitting' the pin, 67 extending eccentrically from the disk 68which fits a counterbore 69 formed eccentrically in a driving membersuch as thev gear 70. The disk, 68 is rigid with the shaft lll; forexample said disk may be keyed to said shaft by a key 68` as shown, saidshaft being supported for rotary motion .by the elongated hub 72 of saidgear 70 and extending outward beyond said hub for a purpose that willhereinafter appear. By rotating theshaft 71 the disk 68 can be turned soas to bring the axis of the stud or pin 67 into coincidence with theaxis of the gear 70 or at various points removed rom said axis by reasonof which the stroke of the lever 55 can be varied or said/lever alsothrown out of action during the rotation of the gear 70, the lastmentioned action occurring when the` axes of the pin 67 and gear 70 arecoincident as shown in Fig. 2. The hub of the gear70 may as shown be setinto a bearing sleeve 73 fitted in one side of the column 11. In meshwith the spur gear 70 is -t-he pinion 74 fastened to the power shaft 75which may be driven in any desirable manner for instance by a pulley 76.It will, therefore, be clear that when the shaft 75 is being rotated theslide 36 and therefore the tool 31 through the intermediate parts willbe reciprocated, the length of the reciprocation depending upon thedistance of the stud 67 t :from the axis of rotation of the spur gear70.

Vire desire to call attention to the fact that the lever 55 iscounterbalanced Which result tion or rocking movement, between it sendsand the mass of the weighted arm of said lever is sufiicient tocounterbalance or counterpoise the parts connected withthe inner arm 'ofsaid lever ,including said inner arm itself, so that there is notendency on th'x part ot said lever thc slidel 30 or the parts connectedtherewith to move of them! sclves, by virtue of which the only thingnecessary for the lever-operating mechanism to do, is to actuate saidlever and therefore the varioiis parts ci nnectedtherewith which aswill. be clear is highly advantageous. We desire also to call attentionto thc fact that the mechanism for adjusting the slide 30 to govern theposition at which the tool makes its cut, is connected with said lever55 at one side of its axis of oscillation, while thc .cupped cap-plate.78, and the reduced p0rtioii 7S) of the shaft Tlextends through aperforati n-.in said cap plate and is provided with holding and checknuts 80. By unlooseiiing these nuts 80 the shaft 71 can be freely turnedto adjust the stud G7, and when the adjlistn'ieiit is obtained said nutsl will be tightened'. The means shown for rotating the shaft 7l andtherefore adjusting the stud G7 will be hereinafter described.

y The cap plate 78 is shown provided with a hollow stud or tubularprojection 8l having a lateral oii'set S2 in which is fitted the pin S3,the axis of which is substantially coincident with the axis of rotationof the spur gear 70. The pin may be driven into a hole in said oii'set.It is provided with a sleeve Si having the gear 85 integral therewith,said sleeve extending through a hole in the outer wall of the shell-likecam SG and being as shown keyed to said cam. It, therefore, follows thatlwhen the cam SG is turned the gear S5 will also be turned. The gear 85is in mesh with a gear S7 at the oute'i` end V' df the shaft 88, saidshaft being provided at its inner end within the cup-like cap plat-e 7Swith a gear 89 in mesh with the gear 90 fastened to the Areduced portionT9-of the shaft 71. It will be clear that owing to the describedconstruction the stud 6T .is adjnsted by rotating the cani 8G, and thiscam which receives its motion from the main vshaft 75 also serves tooperate through in- -terniediate connections described below theslide-operating shaft 1.6 to which We have already referred. It will,therefore, be understood that notwithstanding the fact that the strokeof the tool is varied, the slides (12 or 13) when operated by power willcommence their movements Aat the proper times, By virtue of this last'mentioned feature the feed 'of the slides 12 and 13 is'insnied at theexact point notwithstanding the.

adjustme t of the lever pr .analogous member.

'lhe cam SG has an exterior rroove 91 which receives a stud 92 on onebranch of theangle lever 93.fulcrumed at its angle tothe framing of themachine, the other arm of said angle lever being connected with a rod942 jointed at its lower end t the crank arm 95 fastened to the shaft16;y It, therefore, follows that wheii the gear'O driven -'from the.main shaft as already described is rotated it cscillates through thedescribed parte the. lever 55 and also rotates the cam Sti whereby saidcam will 'through the described parts rock the shaft 1G to effect theaction by power, of one of the two slides 13 and 13.
